The association between periodontitis and the impact of oral health on the quality of life of individuals with psoriasis and psoriatic arthritis

Abstract

ABSTRACTObjectiveTo evaluate the association between psoriasis (PSO), psoriatic arthritis (PsA) and periodontitis (PE), and the Oral Health-Related Quality of Life (OHRQoL) impacts on individuals with psoriatic disease’s daily activities compared to the non-psoriatic ones.Materials & Methods296 individuals with psoriatic disease (PSO n= 210, APS n= 86) (cases) and 359 without these diseases (controls) were included. Complete periodontal examinations and collection of variables of interest were performed. The Brazilian version of theOral Impacts on Daily Performance(OIDP) instrument was applied.ResultsThe prevalence of PE was higher in PsA (57.0%; OR=2.67 95%CI 1.65–4.32; p<0.001) than in PSO (34.3%; OR=1.05 95% CI 0.73–1.51; p<0.001) compared to controls (33.1%). Both PsA and PSO groups showed more sites and teeth with 4-6mm probing depth (PD) and had higher OIDP scores than controls (p<0.001), thus indicating worse self-reported quality of life. PE, PSO+PE and consumption of alcohol/anxiolytics significantly influenced OHRQoL (p<0.05). The influence of periodontal parameters on OHRQoL was observed for the presence of PE; PD >6 mm; clinical attachment level >6 mm; higher plaque index, % sites and teeth with bleeding on probing (p<0.05).ConclusionNegative impacts of PE on the OHRQoL were demonstrated. The ones having PSO and especially PsA and PE presented significantly worse indicators.
